Applicatienfiled November 23, 1899. Serial No. 738,030. (No model.)

To all whom, it ma concern:

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusettahavei invented certain new and useful Improvements in Seam Rubbing and Cleaning Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to boot and shoe machinery, and more particularly to machines for rubbing or cleaning the seam which unites the outsole t0 boots and shoes and to certain improvementsv on the seam rubbing and cleaning machine disclosed in Letters Patent of the United States No. 627,185, issued to me on the th day of June, 1899.

The object of the present invention is to provide, in a seam rubbing -and cleaning machine, means whereby a cleaning liquid, such as water ora solution of water and gum, may be applied to the stitched surface to facilitate the cleaning thereof and also to provide in such machines means for keeping the seam rubbing and cleaning tool clean during the operation of the machine.

To the above end the present invention consists of the devices and combination of devices which will be hereinafter described and claimed.

The present invention is illustrated in the accompanying drawings, in which Figure 1 shows in side elevation a seam rubbing and cleaning machine embodying the same. Fig. 2 shows the machine in front elevation. Fig. 3 shows afront elevation of the seam rubbing and cleaning tool. Fig. 4 shows a tool in side elevation. Fig. 5 shows a plan view of the lever which supports the brush for cleaning the seam rubbing and cleaning tool. Fig. 6 shows the eccentricshaft upon which the lever shown in Fig. 5 is mounted. Fig. 7 shows an end view of the eccentric-shaft. Fig. 8 shows in front elevation the tube for supplying the cleaning liquid to the seam. Fig. 9 shows a longitudinal sectional View of the tube.

The frame 1 supports in suitable bearings 2 the driving-shaft 3, which is driven bysnitable pulleys 4 and 5 and which atits forward end carries the crank 6, which oscillates the sleeve 7, carrying the seam rubbing and cleaningtool 8.

Supported in front of the seam rubbing and cleaning tool is the guard 9, and as said tool is oscillated the work is held against the work ing face of said tool by a work support and presser 10, carried by a reciprocating slide 11, which is advanced by means of a bell-crank lever 12, oneend of which is connected by means of a spring 13 and a rod 14 to a foot treadle. (Not shown.) All of the parts so far referred to are, except as hereinafter set forth, substantially the same as corresponding parts of the machine of the patent hereinbefore referred to and need specifically described.

For the purpose of supplying cleaning liquid to the stitches adjacent to the point of operation of the seam rubbing and cleaning not be herein tool 8 there is fixed to the front bearing 2 the bracket or arm 15, which carries a clampbearing 16, in which is held a pipe 17, which leads from a tank or reservoir containing the cleaning liquid. (Not shown in the drawings.) The pipe 17 discharges into a pipe 18, (shown in detail in Figs. 8 and 9,) which pipe 18 is fixedly secured by means of a suitable clamp 19'to the tubular sleeve 7, which car ries the seam-rubbing tool 8, and said pipe 18 is bent or offset, as shown clearly in Fig. 9, whereby its lower end will be brought adjacent to the side of the seam rubbing and cleaning tool 8. Inasmuch as the pipe 18 partakes of the oscillating movement of the seam rubbing and cleaning tool its upper end is formed bell-shaped or provided with a funnel 20 in order that its lateral movement may not interfere with the proper discharge of the cleaning liquid therein from the pipe 17.

The lower end of the pipe 18 is beveled, as shown at 21, substantially like the bevel of the working face of the seam rubbing and cleaning tool 8, and in the lower end of the pipe 18 there is provided a perforated plate 22, out of which the liquid is discharged onto the seam adjacent to the point of operation of the tool.

During the operation of the seam-rubbing tool on the stitches it removes any surplus was or other dirt which may have been deposited thereon, and this wax and dirt will in time clog the grooves of the tool, and therefore in the machine of the drawings there is arranged a device to keep the tool clean. This device consists of a rotating brush 23, which is secured to one end of a shaft 24, mounted in bearings 25, carried by a lever 26, (see Fig. 5,) the bearings being supported by the forwardly-extending arms 27 of said lever. The lever 26 carries at its rear end arms 28, which supportbearings 29, arranged to be mounted upon the end of an eccentric-shaft 31, which is adjustably mounted in a bearing 32, formed in the fixed frame of the machine, said shaft being held in the bearing 32 by means of a set-screw 33.

By forming the shaft 31-, which supports the lever 26 as an eccentric, the position of the brush 23 with relation to the tool 8 may be adjusted, as the turning of said shaft in its bearing will move the lever 26 and the brush 23 toward or away from the tool 8,

Upon the shaft 24 between the bearings 25 is mounted a pulley 34, and upon the shaft 30 between the bearings 29 is mounted a pulley 35, having two belt-grooves 36 and 37. A belt or cord 38 passes from the belt-groove 36 of the pulley to the pulley 34 and imparts a rotary motion to the shaft 24 and the brush 23. The pulley 35 is driven by a belt 39, which engages the groove 37 and which in turn is driven by a pulley 40 on the main shaft 3, the belt 39 passing around idle pul leys 41, supported on a bracket 42, fixed to the side of the frame by a set-screw It is to be seen that a rotation of the shaft 3 will, by means of the belts 30 and 38, impart a rotary motion to the brush 23, which when said brush is brought into the position shown in Figs. 1 and 2 of the drawings will brush and remove from the grooves of the seam rubbing and cleaning tool any wax or other dirt which may have accumulated therein. Of course the brush should not be brought into contact with the tool while said tool is operating to rub and clean the stitches of a seam, and it therefore becomes necessary to move said brush out of the way while the shoe is presented to the operation of the tool, and while the moving of the brush into and out of operative position may be accomplished in any suitable way and its movements, if desired, left entirely to the judgment of the operator I prefer to so arrange the brush that it will be automatically thrown into operative position upon the removalof a shoe from the machine and to be automatically thrown out of operative position when a shoe is presented to the Workin g face of the seam-rubbing tool. To secure the above-suggested result, I have arranged the lever 26, which carries the brush 23, to be rocked about the shaft 30 on the advancement of the work support and presser 10 to force the shoe against the rubbing-face of the tool 8 to depress the forward end of said lever and remove the brush from operative position and to rock the lever about the shaft in the opposite direction to raise its forward end and place the brush in operative position upon the retractive movement of the work support and presser 10, and this is accomplished in the machine of the drawings as follows: The lever 26 has projecting at its rear end an arm 44, to which is connected a spring 45, the lower end of which is connected to the forward arm of the bell-crank lever 12, such spring acting to raise the lever 26 to the position shown in Figs. 1 and 2 of the drawings to throw the brush into operative position.

For the purpose of depressing the forward end of the lever 26 there is provided a link 46, which is pivotally connected at 47 to the forward end of the bell-crank lever 12 and which at its upper end is slotted, as shown at 48, and embraces a stud 49, fitted in an ear 50 of the lever 26, said link 46 also being connected to the lever 26 by means of a spring 50*, which at one end engages the stud 49 and at its opposite end a pin 46* in the link 46. The slotted connection between the link 46 and the lever 26 provides for lost motion, so that while the brush 23 and the work rest and presser 10 are actuated simultaneously by connected mechanisms they may nevertheless have a certain amount of independent movement. The above arrangement is such that as the bell-crank lever 12 is drawn-down by the foot-treadle to advance the work rest and presser 10 the link 46 and spring will draw down the forward end of the lever 26 and remove the brush 23 out of the way of the shoe and out of operative position, and as the work rest and presser is held in its advanced position to force the seam of the shoe against the rubbing-face of the seam rubbing and cleaning tool during the operation of the tool on the seam the cleaning-brush will be held in its depressed position during the operation of such tool. As soon as the rubbing and cleaning of the seam has been completed the removal of the foot from the foot-treadle permits the spring 51 to retract the slide carrying the work rest and presser 10 and permits the spring 45 to raise the lever 26 and place the brush 23 in the position shown in the drawings, in which position it will act on the grooved rubbing-face of the tool and clean the tool.

Like the machine of the patent the present invent-ion comprises means for heating the tool, which consists of a pipe 52, supported adjustably on the side of the frame by means 7 of a clamping-plate 53 and set-screw 54, the forward end of the pipe 52 being provided with any suitable burner for any suitable gas,

\Vhile I have in the foregoing specification set forth the present invention as being em- -bodied in the machine of my patent referred to, it will be understood that its application is in no manner limited thereto;

The operation of the machine hasbeen sufficiently described in connection with the foregoing description of its form and arrangeinent, and any further description thereof is deemed unnecessary.

Having described the construction and mode of operation of my invention, I claim as new and desire to secure by Letters Patent of the United States- 1. In a seam rubbing and cleaning machine, the combination with a seam rubbing and cleaning tool constructed and arranged to act in the crease between the upper and sole of a shoe, of a liquid-supplying device having a part also arranged to enter the crease between the upper and sole and supply a cleaning liquid to the stitches of the seam adjacent to the point of operation of the tool, substantially as described.

2. In a seam rubbing and cleaning machin e, the combination with a seam-rubbin g tool constructed and arranged to act in the crease between the upper and sole of a shoe, of a clean ing device for cleaning the rubbing-face of said tool and means for actuating said cleaning device, substantially as described.

3. In a seam rubbing and cleaning machine, the combination with a seam rubbing and cleaning tool, of a tool-cleaning brush and the combination with a seam rubbing and cleaning tool, of a work rest and presser, a tool-cleaning brush, and connected mechanisms for actuating the work rest and presser and tool-cleaning brush, whereby said brush will be thrown into or out of operative relation to the tool as the work rest or presser is retracted and advanced, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. HADAWAY.
